I just noticed, that mkgmap changed the files it outputs on an empty command just again...

java -jar mkgmap.jar --latin1 --overview-mapname=test1 --tdbfile --index

used to produce at least either:
mdr*.tmp
or
test1_mdr.img
now however (since integration of the overview2 branch?) - no files are output at all anymore...

it would be great if there was a possibility to check for
a) mkgmap working (check if working very basic/only react if correct Java installed, and output a file - even without input)
b) best would be if that file could contain the mkgmap version number - so right now 2641...

or am I missing something - and what I want to achieve is already possible?
